LINER FOR CENTRIFUGAL LlQUlD-SEPARATORS.

Application filed January 4, 1902.

To (tZZ whom it ntay concern:

Be it known that I, NICHOLAS IV. GALES, a citizen-of the United States, residing at VVater- 100, in the county of Blackhawk and State of Iowa, have invented certain new and useful Improvements in Liners for Centrifugal Liquid-Separators, of which the following is a specification.

My invention relates to improvements. in liners for centrifugal liquid-separators, and especially to the class of liners which are composed of superimposed separated conical disks; and thelobject of my improvement is to so vary the form of the disks and the them as to delay the movement of the milk in the separator-bowl, and thereby induce more thorough separation of the cream therefrom. This object I attain by the means illustrated in the accompanying drawings, in which Figure l is a vertical section ofa separatorbowl containing my improved form of liner. Fig. 2 is a perspective view ot the milk inlet and distributing tube, and Fig. 3 is a perspective view of one of the conical disks.

Similarletters refer to similar parts throughout the several views.

The separator-bowl shown is constructed in lower part it. About the central point of the bottom of the inner side of the bowl is fitted a boss g, which engages the inner side of the lower end of the milk-introduction tube at, keeping the latter in its proper position within the bowl. The milk-introduction tube a has its upper end open for the introduction of milk from without and is also provided with oblong openings b near its lower end, so

into the receiving-cone cl,'the latter being joined to the tube a above and having its lower edge in contact with the bottom of the inside of the separator-bowl and being rendered leakage-proof by means of a rubber ring f, placed in a groove in its lower edge and compressed between it and the bottom of the inside of the bowl. In the upper horizontal surface of the truncated cone 01 openings n are placed, extending from above down ward to form creamexits for such of the cream as is separated within said cone. Sev- Serial No. 88.372. (No model.)

eral milk-exit tubes are placed along the inner wall of the cone (Z, their upper ends passing through the cone justoutside of the truncated edge thereof. these milk-tubes are but a short distance above the bottom of the bowl 72,. The remainder of the interior space of the bowl is nearly filled with a series of super-posed conical disks In. These disks are stepped or corrugated concentrically, and a numberofshort tubes m are fixed within the upper part of each at such a distance from the axis of the bowl as to bring them just Without the clear cream zone thereof. These openings may be formed by either punching holes through the disks, leaving raised rims around them, or by introducing short tubes. The lowermost of the disks it rests just above the coned and is supported above it by the outer edges'of the milk-tubes o.- In like manner each of the other disks 76 when superposed over the one below it'is supported a short distance above such lower disk by means of the'outer edges of the rims of the short tubes or punched openiugsm.

The lower ends of Several tubes e for the exitof the skimmed milk are fixed radially about the inner periphery of the upper portion 71 of the bowl, their inner ends opening near the inner periphery of the lower portion h of said bowl. The other ends pass through the upper portion of the bowl. A cream-exit o is placed within the upper portion of the bowl.

The method of operation of my improved liner is as follows: Milk being introduced into the tube a passes thence through the openings 1) into the innerchamber bounded by the cone 01. There, through the influence of centrifugal force, it is projected radially against the inner periphery of the cone and undergoes a partial separation, the cream passing upward through the holes a into the cream zone of the separator-bowl. The milk which has thus been partially deprived of its cream, being by its greater weight deflected to the inner periphery of the cone'cl, is forced up ward through the tubes 0 into the interior of the bowl h, arriving in said bowl at points just outside the pure-cream zone thereof. The short tubes n of the conical disks 7c are situated at the same distance from the axis of the bowl as is the upper end of the tube c.--

Portions, of the milk issuing from the tube are forced upward through the short tubes 171. Such particles of the milk as are not caught by the short tubes m are flung out radially and contact with the surfaces of the conical disks 7;, passing over them, the heavier watery particles of the liquid separating in transit from the lighter, the heavier particles seeking the inner periphery of the bowl, and the lighter particles seeking the cream zone surrounding the axis of the bowl.

Somewhat similar forms of separator-liners have heretofore been constructed; but it is believed that the peculiar form of construction here shown tends to a greater thoroughness in the separationof the milk than any other of said forms. This greater thoroughness in separation is due first to the manner of introducing the partially-separated milk through the tubes 0 into the inner chamber of the separator at points just without the cream zone thereof and the prolongation of the separation caused by the partial passage of the milk through the short tubes m and the increase of frictional resistance to the flow of the milk by reason of increasing the surface areas of the conical disks by stepping or corrugating them. The retardation induced by said increased frictional resistances and by the interference caused by the angles of the corrugations crossing the radial lines along which milk tends to be carried by centrifugal force greatly increases the effectiveness of the separator. Another advantage results from the fact that whatevercrearn is skimmed from the milk while the latter is yet within the chamber in the cone d is brought directly into the cream zone in the interior of the bowl, and a remixing of it with the partiallyseparated milk in the bowl is avoided. This vexpedites the process of separation.
